Energy Conservation Problem?

  1. Jul 31, 2009 #1
    While just standing on creaking floorboard, i was thinking about where the energy came from to create the noise.

    I assume it came from me moving my mass over the creaky point, therefore do i lose more energy walking on creaky floorboards than just normal floorboards?

    Yes, you lose more energy on creaking floorboards. The up and down motion of the flexing of the floorboards absorbs energy. It's like you're walking uphill.

    Hmm, I remember stories about walking uphill both ways. I guess it is possible :smile:
